[0038] The device in the scheme is mainly installed between the engine and the oil tank, so that the oil in the oil tank enters the engine and is filtered first. The water in the oil can be filtered, and the impurities in the oil can be blocked. The inside of the filter tank body 1 is hollow, and a filter device 8 for filtering is arranged in the inside. The filter device 8 is mainly used for filtering water and impurities in the oil. A dirt outlet 7 is installed at the outer end of the filter tank body 1. The dirt outlet 7 is mainly used for discharging the impurities and water filtered out by the filter device 8 in the filter tank body 1, and can also be used for sampling and analyzing the filtering effect. A tank cover 2 is detachably installed at the top of the filter tank body 1. The tank cover 2 covers the filter tank body 1, so that the inside forms a sealed state. A fixed support 6 is fixed to the outer end of the tank cover 2, so that the filter tank body 1 can be installed on the vehicle frame through the fixed support 6. An oil inlet 3 and an oil outlet 4 are fixedly installed at the top of the tank cover 2. The filter device 8 divides the inside of the filter tank body 1 into two spaces. The outer cavity is used for oil inlet, so that the oil enters the inner cavity after being filtered by the filter device 8.

[0039] A clamping assembly 5 is installed on the oil inlet 3 and the oil outlet 4, which is used for installing the oil conveying pipe. When the oil conveying pipe is installed on the oil inlet 3 or the oil outlet 4, the oil conveying pipe is sleeved on the outer surrounding of the inner pipe 52, so that the oil conveying pipe is located in the installation gap. Then the movable sleeve 53 is rotated to move forward along the outer pipe 51, so that the inclined surface one 58 on the pressing block 54 presses the inclined surface two 511 on the clamping block 55. Thus the clamping block 55 is pushed into the installation gap between the outer pipe 51 and the inner pipe 52, and tightly abuts against the outer part of the oil conveying pipe.

[0041] The tray 9 is fixed on the inner side wall of the filter tank body 1. A recess for installing the filter device 8 is arranged on the tray 9. After the filter device 8 is placed in the recess on the tray 9, the filter device 8 is clamped between the tray 9 and the tank cover 2. The filter device 8 is mainly composed of an inner cylinder and a filter core. The filter core is made of glass fiber. The filter device 8 mainly filters through the physical property difference and the action of special materials. The molecular structures of fuel and water are different. The water molecules have strong hydrogen bond action and are easy to gather into water droplets, but the fuel does not. The hydrophobic filter core such as glass fiber can allow the fuel to pass through while blocking the water droplets, so that the water is gathered and settled, thereby blocking the water outside the filter device 8, and completing the filtration of water and impurities.

[0042] Please refer to Figure 3 , the oil outlet assembly 10 comprises an oil pipe 101, the bottom end of the oil pipe 101 extends through the tray 9 to the bottom of the filter tank body 1 and is fixedly installed, and the filter device 8 is sleeved outside the oil pipe 101.
